Καταλήγοντας, θεωρούμε -όπως και η πρόσφατη
βιβλιογραφία- ότι για την ανάπτυξη εγκεφαλικού εμ-
φράκτου περισσότερη σημασία έχει η ποιότητα της
αθηρωματικής πλάκας και λιγότερο ο βαθμός στένω-
σης των καρωτίδων. Η υπερηχογραφία σαν μέθοδος
διερεύνησης των καρωτίδων είναι πολύ σημαντική τόσο
στην ανίχνευση της καρωτιδικής νόσου όσο και στον
σχεδιασμό της θεραπευτικής αγωγής.

Cor-
relation of carotid artery lesions, using color Dop-
pler US, with ischemic cerebral lesion
The purpose of this study is to evaluate extracranial
carotid artery lesions using color Doppler ultrasound
(CDUS) and to correlate these findings with ischemic
cerebral lesions revealed by CT and MRI. 116 patients
(85 males/31 females) with an average age of 68 years
were examined during a 5 year period. All these patients
exhibited clinical signs of possible stroke. A brain CT
scan was performed on all of the patients and 24 of
them were also examined using MRI. CDUS was used
to examine the extracranial portion of their internal
carotid arteries and assess the quality of the revealed
atheromatous plaques (regarding their echolucency, the
presence of calcifications and the stenoses induced by
them). The CT scans of 53 patients revealed ischemic
lesions or intracerebral hemorrhage. U/S examination
of their carotid arteries found atheromatous plaques
to 107 of the patients, 10 of which were ulcerated.
33 of the patients had internal carotid artery stenoses
greater than 50% and 20 of them had stenoses greater
than 70%. The quality and extent of atherosclerotic
lesions in the internal carotid arteries and the degree
of stenosis they induce, correlate directly with CT and
MRI findings of ischemic stroke.
